In the end, I found a solution, I'm writing this just in case someone had the same problem. Although I can't find the menu item, "Organize bookmarks" can be accessed using the Ctrl+Shift+B shortcut.
Hi, I need to restore a previous version of bookmarks, since all my bookmarks on all the computers are just gone. I've found an ok version in the cometmarks page bookmarks->history, but only a button "view differences" was accessible. Is there a menu to restore the bookmarks in cometbird, I couldn't find it? (Cometbird 11.0, CometMarks 2.5) Thanks, Katerina
